 # livekit-agents
+
 Example agents I've built using the LiveKit Agents (https://github.com/livekit/agents) framework
+
+## To run any of these agents
+
+1. `cd` into agent subdirectory
+2. `cp .env.example .env`
+3. open the `.env` file and replace `XXXXXX` with proper values for each environment variable
+4. `python agent.py start`
+
+## To interact with the agent in the agents playground
+
+1. open a browser and navigate to: `https://agents-playground.livekit.io/`
+2. choose to the same LiveKit Cloud project that the agent is running against (or manually enter a websocket URL and participant token if self-hosting)
+3. click `Connect` in the top right corner of the playground UI
